Remove old billing interface

[Jeff Godin]

The old billing interface still exists in master, though it does not appear to be exposed in the UI, and may no longer be maintained / usable.

I am proposing that the old billing interface and references to it be removed.

Branch which should accomplish the proposed removal of the old billing interface is at user/jeff/lp854951_remove_old_billing_interface

committed to master and rel_2_1. Thanks! #811175 is the last related one we need to knock out.
